About light fitting & lighting installation in City of London

Lighting installation covers everything from replacing a single pendant fitting to a full room redesign with recessed downlights, dimmer controls, and LED conversion. The electrician plans the circuit layout, runs cables through the ceiling void, cuts holes for downlights or mounts surface fittings, and connects everything to a properly rated lighting circuit. Modern LED lighting dramatically reduces energy consumption while improving the quality and control of light in your home.

Lighting circuits operate at 6A and use 1.0mm² or 1.5mm² cable — different from socket circuits. Incorrectly wired lighting causes flickering, overheating, and fire risk, particularly with recessed downlights where heat dissipation and fire-rated housings are critical. Work in bathrooms and outdoors is notifiable under Part P. Even in other rooms, modifications to lighting circuits must comply with BS 7671 to be safe and insurable.

Regulations & standards

Part P of the Building Regulations (Approved Document P): Lighting work in bathrooms (zones 0, 1, and 2), kitchens, and outdoors is notifiable. New lighting circuits anywhere in the home are also notifiable. The work must be carried out by a registered electrician or inspected by Building Control.
BS 7671:2018+A2:2022 (IET Wiring Regulations): All lighting installations must comply with the Wiring Regulations, including circuit protection (6A MCB), cable sizing, and the specific requirements for bathroom zones (Section 701).
BS 476 / BS EN 1365 — Fire Resistance: Where downlights penetrate a ceiling that acts as a fire barrier (most ceilings between floors), fire-rated housings must be used to maintain the fire integrity of the ceiling. Intumescent covers are required above the fitting.

Light Fitting & Lighting Installation FAQs

How many downlights do I need per room?

A common guideline is one downlight per 1.2-1.5m² of floor area for general lighting. A 4m x 4m room (16m²) typically needs 10-12 downlights in a grid pattern. Your electrician can advise on spacing and positioning for even light distribution.

Can I replace a pendant light with downlights myself?

Replacing a pendant with a single new pendant on the same circuit is a simple like-for-like swap. However, converting from a pendant to multiple downlights involves running new cables, cutting holes, and potentially adding a new circuit — this should be done by a qualified electrician.

Do LED downlights really save money?

Yes. A 50W halogen GU10 replaced with a 5W LED GU10 saves about £7 per bulb per year at average UK electricity rates. A room with 10 downlights saves approximately £70 per year. LEDs also last 25,000-50,000 hours compared to 2,000 hours for halogens.

What is the difference between warm white and cool white?

Colour temperature is measured in Kelvin (K). Warm white (2700-3000K) gives a cosy, yellowish light similar to a traditional bulb — best for living rooms and bedrooms. Cool white (4000K) is brighter and crisper — suited to kitchens and bathrooms. Daylight (6500K) is very bright and blue-toned.

Can I dim LED lights?

Only if both the LED lamp and the dimmer switch are compatible. Look for lamps labelled 'dimmable' and use a trailing-edge (LED) dimmer switch rather than an old leading-edge dimmer. Your electrician will specify compatible combinations.

Do I need fire-rated downlights?

Yes, wherever the ceiling forms a fire barrier — typically any ceiling between floors in a house or flat. Fire-rated downlights maintain the 30-minute fire resistance of the ceiling. Ground-floor ceilings with no room above (e.g., a bungalow) may not require them, but fire-rated housings are still considered best practice.
